your doing cardio, of-course your going to get tired. also you aren't getting enough food into your system on a daily bases so this could be why you feel fatigue at times. I suggest eating more and getting the protein and vegetables etc. that your body needs. If your doing just cardio, I would also suggest getting some multivitamins so your body i completely healthy.

Well i am trying to lose the loose fat on my body....so how can i eat more if i want to burn more calories then i consume?

You might be eating TOO little... You have to cover your basic needs at least... So keep it less than you burn but up the calories that you intake a little too... Thats all I can say not knowing how much you bring in each day... Cutting weight and starvation are two different animals..
